- The relative degree of mixture with a base metal. 成色，纯度和基本金属的相对混合程度。
- After welding is complete, they shall be removed flush with the base metal without undercutting. 焊接完成后，应清除这些临时部件至与母材金属表面齐平，不得出现咬边。
- The weld overlay cracking can not propagated into the base metal, due to highly fracture toughness of base metal. 相脆化与使用时的氢脆可使堆焊层金属的塑性降到很低值，使得堆焊层的高应力部位萌生开裂。
- Frequency ERW pipe weld heat treatment to achieve the basic performance level of the base metal, and some even beyond. ERW焊管焊缝中频热处理后各项性能也基本达到了母材的水平，部分甚至超越。
- Fracture toughness of heat affected zone (HAZ) was between the base metal and weld metal. 焊接热影响区的断裂韧性介于母材和焊缝金属之间。
- Cold lap is a condition where the weld filler metal does not properly fuse with the base metal or the previous weld pass material (interpass cold lap). 冷隔？（未熔合）由于熔敷金属没有很好的与母材熔合或没与前道焊缝熔合（层间未熔合）。
- Release of the welding energy instantaneously raises the contact point between the thermocouple wire and the base metal to the melting tempera ture and a fusion weld is formed. 焊接能量的释放会把热电偶线和基部材料的接触点的温度升高至熔化温度，然后产生熔化焊接。
- It was shown that the impact toughness of HAZ is 50% of base metal. 结果表明，该钢的焊接热影响区的冲击韧性较母材降低50%25以上；
- We cannot transubstantiate base metals into gold. 我们不能把贱金属变成金子。
- We can't transmute base metals into gold. 我们无法使贱金属变为黄金。
- As to X60 SSAW pipes, the strength of base metal and weld was almost the same, but a big difference was found between the base metal and weld of X52 ERW pipes. X60 SSAW焊管母材与焊缝强度基本相当,X52 ERW焊管母材与焊缝区域存在着较大的强度差异。
- The supposed conversion of base metals into gold or silver in alchemy. 转变在炼金术中假想的从贱金属到金或银的转变
- In this paper, measures to decrease the tensile strain of weld by heating the base metal near the Brittle Temperature Range (BTR) with an auxiliary heat source are described. 本研究通过辅助热源加热脆性温度区间附近的母材金属使之膨胀以减小焊缝所受的拉伸应变。
- The weld overlay cracking can not propagated into the base metal,due to highly fracture toughness of base metal.The serviceability of hydroprocessing reactors is not affected b... 由于壳体基材有高的断裂韧性,堆焊层裂纹不会扩展到壳体基材,堆焊层裂纹不影响加氢反应器的使用性。
